Holy Velocity! The world's fastest zip-line takes riders on a 100mph whizz over a quarry lake...
ZipWorld Bethesda, in Snowdonia, Wales, is also Europe's longest zipline.
After building confidence on a shorter, slower 'Little Zipper' ride, punters strap in for the Full Monty - reaching speeds often in excess of 100mph.
The full experience takes around two hours, and costs €60 (zipworld.co.uk). It runs all-year round, though it is weather-dependent.
